[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0028] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0029] like Figures 1-8 As shown, this embodiment provides a jujube harvesting machine, including a tracked vehicle 1. A collection umbrella 2 is installed at the front of the tracked vehicle. A collection platform 3 is provided below the fruit outlet at the bottom of the collection umbrella. A vibrating tree clamp 4 is provided at the bottom of the collection platform. A front conveyor 5, which drives from front to back, is connected to the rear of the upper surface of the collection platform. An air separation mechanism 6, which is installed on the tracked vehicle, is connected to the rear of the front conveyor. A collection mechanism 7, which is installed on the tracked vehicle, is connected to the rear of the air separation mechanism. The collection mechanism includes a large fruit collection bin 8 and a small fruit collection bin 9. A vibrating screen 10 is provided between the large and small fruit collection bins.

[0030] The collection umbrella is installed on the collection platform and can be opened or closed, which is existing technology.

[0031] The tracked vehicle can move to the underside of the jujube tree, where its vibrating tree clamps hold the trunk. The collecting umbrella unfolds and closes to surround the trunk. The area covered by the closed collecting umbrella is larger than the area of ​​the tree canopy, so when the fruit falls, it will fall into the collecting umbrella.

[0032] As the vibrating tree clamps reciprocate and vibrate, the tree trunk shakes at a specific frequency and amplitude, causing the jujubes to fall off due to the inertial force exceeding the connection force between the fruit stalk and the branch. The fallen jujubes fall into the collection umbrella and are then conveyed by the front conveyor to the air separation mechanism to blow away leaves, dead branches and other debris. The jujubes are then screened by the vibrating screen, with large fruits going to the large fruit collection bin and small fruits going to the small fruit collection bin.

[0033] In this embodiment of the utility model, a first movable seat 11 is provided in front of the front of the tracked vehicle and is adjusted to reciprocate forward and backward by a first drive mechanism. A second movable seat 12 is provided on the first movable seat and is adjusted to lift and lower by a second drive mechanism. A third movable seat 13 is provided on the second movable seat and is adjusted to reciprocate forward and backward by a third drive mechanism. The vibrating tree clamp is installed on the third movable seat.

[0034] The first, second, and third drive mechanisms are all ball screw pairs driven by electric motors; a sliding block slide rail moving pair with front-to-back translational guidance is connected between the first movable seat and the front of the tracked vehicle; a sliding block slide rail moving pair with lifting guidance is connected between the second movable seat and the first movable seat; and a sliding block slide rail moving pair with front-to-back translational guidance is connected between the third movable seat and the second movable seat.

[0035] The first, second, and third movable seats allow for adjustment of the front-to-back position and height of the collecting umbrella, collecting platform, and vibrating tree clamp.

[0036] In this embodiment of the utility model, the vibrating tree clamp includes a sliding base plate 14 connected to a third movable seat body via a sliding block slide rail moving pair guided by front and rear directions. A crank-slider mechanism 15 driven by a motor is also connected between the sliding base plate and the third movable seat body to facilitate the control of the back-and-forth reciprocating movement of the sliding base plate. A left clamping body 16 and a right clamping body 17 are hingedly installed on the sliding base plate. The left and right clamping bodies are opened and closed by a cylinder.

[0037] After the left and right clamps hold the tree trunk, the crank-slider mechanism controls the sliding base plate to move back and forth. The back and forth movement of the sliding base plate causes the tree trunk to shake at a specific frequency and amplitude, causing the jujube fruit to fall off because the inertial force is greater than the connection force between the fruit stalk and the branch.

[0038] In this embodiment of the invention, the bottom of the collection platform is fixedly connected to the sliding base plate, so that the collection platform and the sliding base plate are integrated.

[0039] In this embodiment of the utility model, the collection platform includes a collection trough 19, the bottom of the collection trough sloping downwards from front to back, and the collection trough having an outlet that gradually narrows from front to back at the rear end, which is then connected to the front low end of the front conveyor; the front end of the collection trough has a notch, and a tree clamp is provided on the notch.

[0040] After the fallen jujubes fall into the collecting umbrella, they roll backward through the collecting trough to the lower end of the front conveyor for further transport.

[0041] In this embodiment of the utility model, the tree clamp is composed of a rear clamp body 20, a left front clamp body 21, and a right front clamp body 22. The rear clamp body is installed on the notch and is provided with a plurality of rear elastic telescopic top blocks 23 arranged sequentially from left to right. The left front clamp body is provided with a plurality of left front elastic telescopic top blocks 24 arranged sequentially. The right front clamp body is provided with a plurality of right front elastic telescopic top blocks 25 arranged sequentially. Furthermore, the left front outer shell 26 on the left front clamp body is hinged to the left front of the notch, and the right front outer shell 27 on the right front clamp body is hinged to the right front of the notch. A latch 28 is provided between the adjacent splicing seams at the front ends of the left front outer shell and the right front outer shell.

[0042] The top surface of the left front outer shell is higher than the top surface of the left front elastic telescopic top block, and the top surface of the right front outer shell is higher than the top surface of the right front elastic telescopic top block. The height difference between the aforementioned top surfaces can prevent the jujubes from rolling forward.

[0043] A support rod 29 extending to the left and right is fixedly connected to the middle position of the notch. Each of the rear elastic telescopic top blocks is provided with a groove 30 extending forward and backward. The support rod passes through the groove on several rear elastic telescopic top blocks to support the several rear elastic telescopic top blocks. The groove is provided so that the support rod will not hinder the forward and backward telescopic movement of the rear elastic telescopic top blocks.

[0044] The rear end of each of the rear elastic telescopic top blocks is fixed with a guide sleeve 31. Each guide sleeve is coaxially fitted into the guide rod 32 fixed on the notch. A spring 33 is fitted around the guide sleeve and guide rod between the rear end of the rear elastic telescopic top block and the notch. The guide sleeve, guide rod and spring are hidden inside the collection groove behind the notch.

[0045] The front edge of several rear elastic telescopic top blocks is an arc-shaped contact surface that is concave in the middle and backward.

[0046] The front end of each of the left front elastic telescopic top blocks is also fixed with a guide sleeve. Each guide sleeve is coaxially fitted into the guide rod fixed on the left front outer shell. A spring is fitted around the guide sleeve and guide rod between the front end of the left front elastic telescopic top block and the left front outer shell. The guide sleeve, guide rod and spring are hidden inside the left front outer shell.

[0047] The rear edges of several left front elastic telescopic top blocks are generally arc-shaped contact surfaces.

[0048] The front end of each of the right front elastic telescopic top blocks is also fixed with a guide sleeve. Each guide sleeve is coaxially fitted into the guide rod fixed on the right front outer shell. A spring is fitted around the guide sleeve and guide rod between the front end of the right front elastic telescopic top block and the right front outer shell. The guide sleeve, guide rod and spring are hidden inside the right front outer shell.

[0049] The rear edges of several right front elastic telescopic top blocks are generally arc-shaped contact surfaces.

[0050] As the vibrating tree clamp grips the tree trunk and the collecting umbrella unfolds and closes to surround it, the leading edges of several rear elastic telescopic blocks contact the rear half of the tree trunk. Each rear elastic telescopic block adaptively extends and retracts. The operator manually closes the left and right front outer shells and uses the latches to lock them together, causing the rear edges of several left and right front elastic telescopic blocks to contact the front half of the tree trunk. Each left and right front elastic telescopic block adaptively extends and retracts. The rear elastic telescopic blocks and the left and right front elastic telescopic blocks seal the circumferential gap between the collecting trough and the tree trunk.

[0051] In this embodiment of the utility model, the air separation mechanism includes a rear conveyor 35 installed inside the shell 34 of the tracked vehicle and driven from front to back. A fan 36 installed inside the shell of the tracked vehicle is provided on one side of the rear conveyor in the length direction, and an outlet 37 opened on the shell is provided on the other opposite side of the rear conveyor in the length direction. The fan blows air toward the upper surface of the rear conveyor and the outlet.

[0052] Inclined guide walls 38 located inside the car body are provided on the front and rear ends of the blow-out nozzle.

[0053] The air separation mechanism's blower blows leaves, twigs, and other debris from the upper surface of the rear conveyor out through the blower outlet. This increases the cleanliness of the collected fruit and reduces the workload of subsequent manual sorting, further improving the overall efficiency of fruit collection.

[0054] In this embodiment of the present invention, a guide plate 39 installed inside the vehicle body is provided between the rear end of the front conveyor and the front end of the rear conveyor, and the guide plate is inclined downward from front to back.

[0055] In this embodiment of the utility model, the vibrating screen is inclined downward from front to back, with its upper surface at the high end connected to the rear end of the rear conveyor, and its upper surface at the low end connected to and leading to the large fruit collection bin. The rear end of the large fruit collection bin is provided with an openable and closable bin door 40.

[0056] In this embodiment of the utility model, the small fruit collection bin is located next to the large fruit collection bin. A small fruit guide plate 41 is fixedly connected to the vibrating screen below its screen holes. The small fruit guide plate also tilts downward from front to back, and the lower end of the small fruit guide plate is connected to the small fruit collection bin separately. The small fruit collection bin is provided with a small bin door 42 that can be opened and closed.

[0057] In this embodiment of the utility model, an inclined feeding plate 43 is provided between the lower end of the small fruit guide plate and the bottom of the small fruit collection bin. The feeding plate receives the small fruits rolling off the small fruit guide plate, and the small fruits then roll off the feeding plate to the bottom of the small fruit collection bin.

[0058] In this embodiment of the invention, the bottom of the large fruit collection bin slopes downward along the direction of the large bin door, and the bottom of the small fruit collection bin slopes downward along the direction of the small bin door, so that the fruit rolls out automatically after the bin door is opened, which greatly increases the efficiency of fruit unloading and provides conditions for subsequent fruit processing and handling.

[0059] In this embodiment of the utility model, the working principle of the jujube harvesting machine is as follows: the tracked vehicle can move to the bottom of the jujube tree, its vibrating tree clamp clamps the trunk, and the collecting umbrella unfolds and closes to surround the trunk. As the vibrating tree clamp moves back and forth, it causes the trunk to shake at a specific frequency and amplitude, causing the jujube fruit to fall off due to the inertial force being greater than the connection force between the fruit stalk and the branch. The fallen jujube fruit falls down into the collecting umbrella and is then sent to the wind separation mechanism by the front conveyor to blow away the leaves, dead branches and other debris. The jujube fruit is then screened by the vibrating screen. Large fruits that cannot enter the screen holes go to the large fruit collection bin, and small fruits that enter the screen holes go to the small fruit collection bin.

[0060] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
